//I am Using Laravel I Have Done Order creation

$customerId = customer_id;
// Replace placeholder values with your actual data
$customPriceLevelId = $this->getCustomPriceLevelId('Retail Price'); // Replace with your actual method to get custom price level ID
$stripePaymentMethodId = 7; // Replace with your actual method to get Stripe payment method ID
$otherPaymentMethodId = 1; // Replace with your actual method to get the other payment method ID

        $so = new SalesOrder();
        $so->entity = new RecordRef();
        $so->entity->internalId = $customerId;

        // Set the shipping address details
        $so->shippingAddress = new Address();

        // Add line items to the Sales Order
        $so->itemList = new SalesOrderItemList();
